Cheryl Cole is keen to return to work.

The 'Fight for This Love' singer - who has had to take a break from all her commitments after she was struck down with potentially fatal tropical disease malaria - has reportedly been texting Simon Cowell saying she is bored and wants to resume her role as a judge on his British pop star search show 'The X Factor' as soon as possible.

Speaking to 'GMTV', Simon said: "The worst is over. The texts are getting increasingly feisty so she's on the mend."

However, the music mogul admitted he is trying to stop the 27-year-old brunette beauty - who is believed to have contracted the illness while on holiday with rumoured boyfriend Derek Hough in Tanzania last month - from rushing back to work too quickly.

He explained: "It was serious and she was ill - we didn't realise how ill. But judging by the text messages I've had, she is definitely looking forward to getting back to work.

"I think our job is to make sure she doesn't come back too quickly because I think she's bored out of her mind and going crazy."

Cheryl - who as well as pulling out of 'The X Factor' had to cancel her scheduled appearances at the V Festival in August - was discharged from hospital last Thursday morning (15.06.10) and is now convalescing at her home in Surrey, South England.
